This invention relates to cages for separating; and retaining thefrolling elements of anti-friction 'bearings and has for an v -ji-t to provide a laminated permanently un (Gil structure for/this purpose which is preferably formed from a plurality of super-imposed blanks as one piece in suitable forming diesL' V 1n the accompanying drawings a cage made in accordance with the invention is ill:|. 1i-a't(- d as is also the blank used in the method of format-ion, in which drawings-- Figure 1 is an elevation of my improved cage.

Fig. plane of the lines 2-2 of Figure 1.

Fig. 3 is a face view of a blank which is capable of formation'in the illustrated cage,

and

Fig. '4 is a central cross section of-two blanks super-imposed for the-action of the forming (lies, not illustrated. Y

Hieretofore I have made cages for ball bc'aringsof, a single piece of metal of about the combined: thieknesses of the super-imposed metal illustrated herein, the cages being very similar inshape' to the illustration in Figures 1and2. In certain applications it has been found that more fiexibility'in certain parts of the structure would be desirable.

by the: forming dies of a plurality-of superimposed sheets each considerably thinner inventionand to simplify the description, 8.

blank Sis represented in Figs; 3 and 4 which is 'built up of two similarly formed super imposed members 6 and 7, each of these being of a thickness equal to about one-half the thickness of thepreviously used single or one piece blank. Also for the purpose of description it will be assumed that the blank 6 is the one which will form the member 8-8 of the cage, see Figure 1, andethe sheet 7 of the blank will form the member 9- -9 of the completed cage. .v The form of cage selected for illustration is that which is intended for use uponthe deep groove annular bearing of the Conrad type and preferably of 'thetwo row variety,

2 is a section taken at about the To aflord'this flexibility in those cases where it is needed, I have proposed building the blank which is to be acted upon the application of a single piece cage a two row bearing being illustrated in iny application, Serial; No. 82,558 -filed January 20th, 1926 and renewed December 4th, 1926 I I whit-his now: pending but allowed.

The forming dies will act upon the plu rality of thesesuper-im 'osed blanks as one" piece, thereby forming tese blanks and permanently uniting them into a. single cage.

In the illustration the. separator is shown I drawn from the built up or, laminated piece of sheet metal hereinabove' mentioned and forms two substantially cylindrical. plates 12 and 13 united at one end by a. fold 14. This fold 14 is reallythe bottom or connecting member made by the drawin'g dies. During the drawing operation a series of notches foraifordmg ball pockets'15 are formed in the free edges of the plates. The metal of-each of the blank membersG and 7 during the operation of forming these pockets is extruded in a flange directed away from the respective plates. When these plates are formed quite close together, as .they. are

shown in Figures 1 and 2, the extruded metal is directed toward the outer faces ofthe plates. .Or in other words, the flanges 16 fromlthe laminae of theouter plate are 1 directed outwardly and the flanges 17 from the laminae of the inner plate are directed it inwardly. In the'illustration the flange of the lamina of each plate is shown extending entirely around each ball poeket IS and eontinuing between pockets, see 18-F ig. 2. 1

The curvature of the inner faces of the V pocket forming flanges 16 and 17 is such that they extend above and below thejgreat circle ofthe ball so that the cage will not permit a ball to-either unduly-depress or 1 raise the cage, that is, the ball cannot ride over or underthe cage. It .willzbe apparent that the numberof layers otwhich the :blank is built iup may;

be varied according to different 'requirements and that the ultimate share of the cage herein shown and describe is i'llus trative of the inventiom'and thatother forms may be made for other types. of bearings. f Having described my invention I claim and desire to secure by Letters Patent:

1. A spacing cage for antiiriction bearings consisting of a body portion formed of Super-Imposed permanently united. layers fies V and folded, presenting two plates disposed face to face and provided at intervals in their edges with open notches, and having flanges extending outwardly from the layers at the notches laterally beyond-the faces of the plates and constituting conjointly ball holding sockets.

2. A spacing cage for anti-friction bearingsconsist-in'g of a body portion formed of super-imposed permanently united layers and folded, presentingtwo plates disposed face to face and provided at intervals in their edges with open notches, and 'having flanges extendingv outwardly from the layers at the notches laterally beyond thev faces of the plates and constituting conjointly ball holding sockets, the flanges being continued.

and-extending along the edges of the plates between sockets.

3. A spacing cage for anti-friction bearings consistin of a body portion formed of super-imposed permanently united layers and folded, presenting two plates. disposed face to face and provided at intervals in their edges with-open notches, and having flanges extending outwardly from the layers at the notches laterally beyond the faces of the plates and constituting conjointly ball holdin sockets, the flanges. from all the layers the edges of the plates between sockets.

4. That improvement in the art of form-.

ing anti-friction bearing ringswhich consists 1n first" blanking out sheet metal, then super-imposing a lurality of these blanks between forming ies, and then subjecting such super-imposed blanks as one "piece to the formative action of the dies, thereby producing a single cage.-

5. That improvement in the art of forming ant -friction bearing cages, which conmg continued and extending along.

sists in first blanking out sheet metal, then super-imposing a plurality of these blanks ANDREW H. LINDE.
